The mos Tooth whitening is a procedure that removes stains and various discolorations of tooth surface. Discoloration of teeth may be endogenous and exogenous nature. The aim of this study was to investigate the impact of bleaching combined with daily use of drinks that cause tooth discoloration. Evaluated the changes in surface structure of enamel, and changes in hardness after bleaching. Were 20 extracted teeth. The teeth are marked with longitudinal lines halves (medial vestibular and distal surfaces). Tretitana mesial half of the 16% carbamide peroxide, a distal was left as control. NDT device HL400DL, duroskopskom method of enamel hardness was measured before treatment, after treatment and after remineralization. Olympus inverted microscope GX41 enamel structures were observed in the treated and control half of the tooth. After bleaching there is a difference compared to the untreated surface, that surface is bleached a few shades lighter, but after the use of coffee and soft drinks teeth back to the original dark color. Enamel microhardness after the treatment is somewhat small but not significant. With a magnification of 2000x and see the structural changes in enamel. Tooth whitening, but that the remineralization and the abstinence from prebojenih beverages and tobacco.

Suštinu biološkog lečenja caries profunda čini proces 'ozdravljenja' koji se zasniva na stimulaciji dentinogenetske funkcije pulpe, što omogućava stvaranje mineralizovanog tkiva. U eksperimentalnom istraživanju postavljen je cilj da se skening elektronskom mikroskopijom i polarizacionom mikroskopijom: Analiziraju promene na celularnim i ekstracelularnim komponentama zubne pulpe posle direktnog i indirektnog prekrivanja alkalnim cementom (Dycal), Utvrdi izgled dentinske površine posle direktnog i indirektnog prekrivanja pulpe i Formira predlog za kliničku primenu preparata Dycal ukoliko obezbeđuje dobru i efikasnu dentinogenezu. Ispitivanje je izvršeno na eksperimentalnim životinjama (domaća svinja). Za ovo istraživanje korišćen je alkalni cement Dycal. Na zubima eksperimentalne grupe uradjene su preparacije V klase sa vestibularne strane. Na jedanaest zuba je uradjeno indirektno, a na jedanaest zuba direktno prekrivanje pulpe. Nakon završene preparacije dentin je direktno prekriven alkalnim cementom Dycal. Preko Dycal-a je postavljena podloga cink fosfatnog cementa i materijal za definitivno zatvaranje kaviteta (amalgam). Na zubima gde je urađena perforacija komore pulpe Dycal je ubacivan direktno u komoru pulpe, a preko toga je postavljena podloga cink fosfatnog cementa i kavitet je definitivno zatvaran amalgamom. Adekvatno pripremljeni zubi i pulpa posmatrani su SEM i polarizacionim mikroskopom. Rezultati: Posmatranjem i analizom dobijenih rezultata, na polarizacionom i skening elektronskom mikroskopu u poređenju sa kontrolnom grupom, dobijeni su rezultati koji mogu imati značajnu kliničku implikaciju u biološkom lečenju pulpe. Dycal direktno apliciran u komoru pulpe: uočava se granica između novostvorenog reparativnog dentina u normalnu dentinsku strukturu, sreću se degradirane smežurane ćelije, zapažaju se jezgra kalcifikacije, mladi krvni sudovi i ćelije (fibrociti, histiociti i fibroblasti). Indirektno aplikovan Dycal: uočava se normalna dentinska struktura , jasno su vidljivi dentinski kanalići, a sreće se i atubulusna dentinska struktura, vidi se slika dentinske strukture koja prožima acelularno pulpno tkivo, hipercelularnost na granici stvaranja novog dentina i brojni krvni sudovi. Prisustvo amorfnog kalcifikata dentinske strukture govori o početnom stvaranju barijere od čvrstog tkiva što je cilj eksperimenta. Dobijeni rezultati eksperimentalnim istraživanjem sugerišu Dycal kao dobar materijal za direktno i indirektno prekrivanje pulpe.

Telemedicina je kao sistem pružanja zdravstvene zaštite, definisana od Svetske zdravstvene organizacije (SZO) kao praktična zdravstvena zaštita koja koristi interaktivnu zvučnu, vizuelnu komunikaciju i razmenu podataka. Univerzitetski telemedicinski centar u Kosovskoj Mitrovici obezbeđuje stalnu dostupnost kadra neophodnih specijalnosti za brzu i efikasnu telekonsultaciju u slučajevima kada je ona neophodna ili se nameće kao metoda izbora u pomoći kod postavljanja dijagnoze, ali i planiranja i sprovođenja same terapije. Prikazana je 'store and forward' telemedicinska konsultacija u vidu slučaja normalnog nivoa hitnosti koji je zahtevao interdisciplinarni pristup između stomatologa endodonta i stomatologa oralnog hirurga. Kao pametna veza između telekonsultanata pri Univerzitetskom telemedicinskom centru korišćen je XPA3 online aplikacioni sistem. Nakon adekvatne telekonsultacije u kojoj su učestvovali lekari iz Kosovske Mitrovice, Niša i Podgorice, na pacijentu je uspešno sprovedena endodontsko oralnohirurška terapija, čime je pacijent u potpunosti zbrinut.

There are different stick types and shapes, different root canal preparation techniques, as well as different materials for stick cementing and making annexes around posts. The use of fiber-reinforced resin posts to restore endodontically treated teeth has gained popularity due to its mechanical and esthetic characteristics as well as properties of modern adhesive systems. The aim of this article was to show a clinical technique to reconstruct endodontically treated teeth with great loss of tooth structure using direct fiber-reinforced post systems and direct composite restorations. After the preparation of the root canal and cementation of a FRR post, particular attention was paid to the incremental and curing techniques adopted to reconstruct coronal part of the tooth. It is possible to place of fiber-reinforced resin posts. 

Materials wich use like base,and those used for direct and indirect capping should be, except certain physicalchemical and biological performance have and antibacterial effect, to act after the application on residual microorganisms. The aim of this study is that in vitro display antimicrobial activity of some selected resources that are used to protect the dentin below the permanent restoration, and some of this as medication in treating deep surface carious lesions and to directly cover any caries, either artificially open pulp. Antimicrobial activity was tested against microorganisms. On agar plates into the grooves 4 mm in diameter was inserted freshly prepared paste or base. After inserting the material into the surface of bloî od agar, was performed by incubation under aerobic conditions for 24 h in a thermostat at 37 C. Negative effect on the microorganisms, tested materials, it was estimated by the size of growth inhibition zone.

Vital extirpation is microsurgical intervention.Wellknowing of internal morpfology of pulp cavity and with patience, carefull and precise work is possible to extirpate, dilatate and fil in both distal and mesial root of down molars,even if in mesial root exists two canal (buccal and lingual) what is the ruosh aften finding. Vital extirpation is very frequenthy used method in the treatment of multi-root teeth.It is more requested intervention tlak usnal once,but patients mane less visits at the dentist and the results one good enongh. So, one session method isacceptable as from medical point of view but endodontic too.
